Stimulation Technologies

Introduction

This LAKESHORE ISL Stimulation Technologies training course covers the main aspects of Stimulation Technologies whose main objective is to repair formation damage in order to restore / increase production. This interactive training course starts by presenting the basic concepts for stimulation job design, execution and follow up.

Discussion is carried out on formation damage and its effect on well performance and planning of acid stimulation treatments. Focus is given to the main causes of formation damage (damage during drilling, cementing, perforating, producing and working over wells) and how these may be identified.

This training course will highlight:

• Formation Damage (Definition, mechanism, counter measures, etc.)
• Acidizing (Matrix Acidizing, Acid fracturing, etc.)
• Hydraulic Fracturing Overview
• HSE and Stimulation

The training course will also focus on major areas of Acid Stimulation Techniques, both on theoretical concepts and practical onsite experience. Acidizing with Coiled Tubing will be also discussed in detail, due to its importance in acid placement and formation treatments.

Objectives

By the end of this training course, participants will feel confident in their understanding of:

• Introduction to stimulation operations
• Formation damage mechanisms and their identification
• Brainstorming on skin damage
• Acids reactions and their selection for carbonates and sandstones
• Acids and additives used in matrix stimulation
• Candidate well selection
• Acid treatment design
• Acid placement and diverting technologies
• Acid displacement and flow back
• Laboratory tests
• Acid fracturing design basics
• HSE and acidizing operations
• Safety & quality assurance

Training Methodology

This Stimulation Technologies training course will be presented using properly designed slides, some with animation and several videos on relevant issues. A printed manual containing all the slides and/or electronic form in PDF will be delivered to each attendant. Teaching methods include also calculations on related issues. Several examples of actual Stimulation Programs will be presented.
